Can you survive a grade 3 oligodendroglioma?
High grade/anaplastic (grade 3) About 30 to 38% of people with this type of tumour will survive for 5 years or more after they are diagnosed.
Is oligodendroglioma grade 3 a cancer?
Grade III oligodendrogliomas are malignant (cancerous). This means they are fast-growing tumors. They are called anaplastic oligodendriogliomas.
How fast do Oligodendrogliomas grow?
Grade 2 (low grade) oligodendroglioma: These benign tumors grow slowly. They can be present for years before causing symptoms. They are usually confined to nearby tissue only.
What is an anaplastic oligodendroglioma?
Anaplastic oligodendroglioma is a neuroepithelial tumor which is believed to originate from oligodendrocytes, a cell type of the glia. In the World Health Organization (WHO) classification of brain tumors, anaplastic oligodendrogliomas are classified as grade III.
What is the life expectancy for oligodendroglioma?
As a general rule, people with grade II oligodendrogliomas are likely to live for around 12 years following diagnosis. People with grade III oligodendrogliomas are expected to live an average of 3.5 years.
Can oligodendroglioma metastasize?
Oligodendroglioma is a rare type of primary brain tumor which, like other malignant gliomas, metastasizes very rarely even when in high-grade form.
Are oligodendrogliomas slow growing?
Around 3% of all brain tumors are oligodendrogliomas. The tumors can be fast or slow growing. They are more commonly diagnosed in adults, though young children can also be affected. In rare cases, the tumors can spread through the central nervous system via the fluid around your brain and spinal cord.
Is oligodendroglioma a glioblastoma?
Glioblastoma (GBM) with oligodendroglioma component (GBMO) is a newly described GBM subtype in the 2007 World Health Organization classification. However, its biological and genetic characteristics are largely unknown.
